The torsion beam has the characteristics of simple structure, good integrity and low manufacturing cost, and is mainly used for a rear suspension structure of a middle-low vehicle type below A level at present. The structure of the damper is very simple, namely the damper is generally formed by welding a left trailing arm, a right trailing arm and a cross beam, and a spring seat, a damper mounting bracket, a hub mounting plate and the like are welded on the left trailing arm and the right trailing arm. The hub mounting plate is a mounting base of a car tire and has high required strength and good toughness; the trailing arm mainly plays the constraining role to the front and back and left and right rocking of the car, and simultaneously, the trailing arm is also a welding base of other accessories.
The existing torsion beam longitudinal arm is formed by stamping, buckling and welding or internal high-pressure forming.
The stamping buckling welding mode needs a left welding seam, a right welding seam or an inner welding seam and an outer welding seam because the stamping part is divided into an upper piece and a lower piece or a left piece and a right piece which are respectively designed with dies, and the manufacturing cost is higher. Due to the problem of weld joint arrangement, other parts are difficult to avoid the position of the weld joint when the torsion beam assembly is designed again, and the problem of overlarge weld joint stress is difficult to solve.
The internal high-pressure forming has more influence factors, the loading path area of the forming process curve is narrow, and the optimal forming process parameters are difficult to master. Various types of defects are generated during the forming process.
